1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Neuralized (Neurl) is a highly conserved E3 ubiquitin ligase, which in Drosophila acts upon Notch ligands to regulate Notch pathway signaling. Human Neuralized1 (NEURL1) was investigated as a potential tumor suppressor in medulloblastoma (MB). The gene is located at 10q25.1, a region demonstrating frequent loss of heterozygosity in tumors. In addition, prior publications have shown that the Notch pathway is functional in a proportion of MB tumors and that Neurl1 is only expressed in differentiated cells in the developing cerebellum. In this study, NEURL1 expression was downregulated in MB compared with normal cerebellar tissue, with the lowest levels of expression in hedgehog-activated tumors. Control of gene expression by histone modification was implicated mechanistically; loss of 10q, sequence mutation, and promoter hypermethylation did not play major roles. NEURL1-transfected MB cell lines demonstrated decreased population growth, colony-forming ability, tumor sphere formation, and xenograft growth compared with controls, and a significant increase in apoptosis was seen on cell cycle and cell death analysis. Notch pathway inhibition occurred on the exogenous expression of NEURL1, as shown by decreased expression of the Notch ligand, Jagged1, and the target genes, HES1 and HEY1. From these studies, we conclude that NEURL1 is a candidate tumor suppressor in MB, at least in part through its effects on the Notch pathway.
